Dec 2012 - Math II Discussion

<p>I’m pretty sure it said the distance between the two buildings from the ground? I got 381 and if it was that distance that was be asked for, tan40=320/381.</p>

<p>I ended up finding distance between bottom and i got 381 ft i think</p>

<p>distance = 320/tan40</p>

<p>Was the answer for the question involving 300000 and logn/log something 19?</p>

<p>Yeah, it was 381. I remembered wrong.</p>

<p>Do you remember what question 50 was? I don’t remember what I put for my answer choice.</p>

<p>how about the population of doves?</p>

<p>I remember getting 15 for that question with log n/ log 2 when n was 30,000.</p>

<p>For the population of doves, I got that the population was highest in January of every odd-numbered year.</p>

<p>I must say the collegeboard review book is very misleading</p>

<p>^^ that is correct. and 300000 log 2 was 19. heres my interpretation of the circle C plane M question. [circle</a> - Slimber.com: Drawing and Painting Online](<a href=“http://slimber.com/index.php?image=circle.g271100]circle”>http://slimber.com/index.php?image=circle.g271100)</p>

<p>Wasn’t it 300,000 and not 30,000</p>

<p>Oh okay thankss</p>

<p>Ah, I see what you did with that plane question. I think the problem with your interpretation is that a plane by definition extends infinitely in all directions, so the point C would have to be above the plane and not to the side of it. Like, if the plane of M was the plane (x,y,0), the point would have to be something like (0,0,6) rather than (6,0,0). If my interpretation was correct, it would be a full circle instead and not a semicircle.</p>

<p>Oh… was it 300,000? D:</p>

<p>Misaya, youre correct. My bad, I just totally blanked out and freaked on you guys. Lol… and yes, it was log 300000 / log 2 = 18.5 rounds to 19</p>

<p>@killerskullz, i just plugged it into my calculator, it gives you 18.2</p>

<p>but since it was asking for the least greatest integer your answer still is 19 I’m guessing.</p>

<p>For the question about 4 digit numbers where 3 always follows 2, it was 6 right?</p>

<p>Andhow about the q with (x^2 - y^2) =1 and some more info i can’t remember?</p>

<p>Impreviouss I also got 6 for that one.</p>

<p>For the one about (x^2 - y^2) =1 I don’t remember the letter but I think it was something like (x+y) less than -1</p>

<p>franco i got less than one, i think that was letter choice A.</p>
